I was hoping you might lend a hand. :) OK, now this may show how much I've
forgotten but for the symbol of a diode, the 'arrow' side is cathode and
'plate' side is anode - right ? The schematic drawing of this unit
definitely shows the 'arrow' side towards the +12v source.

Cathode - anode    Right ?

This would prevent reverse voltage but not forward voltage. So I should not
have seen a different voltage on the 'plate' side of the diode - if I
understand correctly.

It's just the other way around, Jamie. Arrow = anode, line = cathode.
Positive to anode and negative to cathode will produce current flow.
